Firefighters have a high incidence of low back pain and injury.
To describe lumbar multifidus and abdominal muscle size characteristics in firefighters and to compare these characteristics to normative reference ranges.
In career firefighters without current low back pain (62 males, 7 females), ultrasonography was used to assess: L4 and L5 lumbar multifidus cross-sectional area (CSA), asymmetry, and thicknesses; and external oblique, internal oblique, and transverse abdominal thicknesses. Comparisons of mean values in firefighters were made to the normative 95% reference ranges for the general population and soldiers.
Mean values for lumbar multifidus and abdominal muscle size in firefighters fell within the 95% reference ranges for the general population and soldiers for all measurements, except L4 multifidus CSA in males and L5 multifidus CSA in females, which were larger in firefighters than the general population.
The majority of lumbar multifidus and abdominal muscle size measurements in firefighters are similar to the general population and soldiers. The larger lumbar multifidus CSA in firefighters compared with the general population warrants further study. These data provide a basis for future research using ultrasonography to assess muscle size in firefighters and other workers in physically-demanding occupations.
消防员下背痛和损伤的发生率较高。
描述消防员腰椎多裂肌和腹肌的大小特征，并将这些特征与标准参考范围进行比较。
对目前无下背痛的职业消防员（62名男性，7名女性），采用超声评估：L4和L5腰椎多裂肌的横截面积（CSA）、不对称性和厚度；以及腹外斜肌、腹内斜肌和腹横肌的厚度。将消防员的平均值与普通人群和士兵的标准95%参考范围进行比较。
消防员腰椎多裂肌和腹肌大小的平均值在所有测量中均落在普通人群和士兵的95%参考范围内，但男性L4多裂肌CSA和女性L5多裂肌CSA除外，消防员的这些值大于普通人群。
消防员腰椎多裂肌和腹肌大小的大多数测量值与普通人群和士兵相似。消防员腰椎多裂肌CSA大于普通人群，这值得进一步研究。这些数据为未来使用超声评估消防员和其他从事体力劳动职业的工人肌肉大小的研究提供了基础。
